I MPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 28,557, dated June 5, 1860.

To all whom it may concern:

Be it known that I, ROBERT BRYSON, of Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in Grain and Grass Harvesters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the annexed drawings, making a part of this specification, in which Figure 1 is a vertical section of'my invention,taken in theline a0 :0, Fig. 2; Fig. 2, a vertical section of the same, takenin the lineg Fig. 1; Fig.3, a horizontal section of the same, taken in the line 2 2, Fig. 2.

Similar letters of reference indicate corre-. sponding parts in the several figures.

y invention consists in suspending the finger-bar by the combined agency of an inclined or vertical bracket, a cylindrical crosshead, and a vertical socket-plate, the said parts beingconstructed and arranged and operating together in the manner hereinafter described.

By'myinvention the use of agate to guide the up-and-down movement of the finger-bar and of auxiliary connections to brace and control the same are dispensed with, and the fingerbar, although it has but one point of connection with the frame, is braced and guided in a very perfect manner, and is free to play up and down at one end without any change in its axial bearing taking place; also, to move at both ends in a perpendicular line, and likewise is capable of turning up against the side of the frame whenever it is desired to transfer the machine from one place to another.

To enable those skilledin the art to fully understand and construct my invention, I will proceed to describe it.

A represents a rectangular frame, which is mounted on wheels B B, the axle O of which is fitted in suitable bearings at the under side of the frame A. The axle O is allowed to turn in its bearings, and the wheels B B are fitted loosely on it, each wheel being provided with a pawl, a, which catches into a ratchet, a, on the axle O, the pawls and ratchets causing the axle to rotate when the machine is drawn forward, but not acting upon it when the machine is backed in consequence of the pawls slipping over the ratchets.

On the axle 0 there is placedabevel-toothed wheel, D, which gears into a pinion, E, on a vertical shaft, F, in the frame A, the upper end of said shaft having a spur-wheel, G, on it, which wheel gears into a pinion, H, on the upper end of a shaft, I, in the frame A, said shaft I having a crank-pulley, I), at its lower end. The vertical shaft F is placed directly over the axle O.

J is the finger-bar, the inner end of which has an inclined bar, K, attached to it. The upper end of the inclined bar K is provided with a crosshead, 0, which is fitted in a vertical guide or socket, L, attached to the frame A. The cross-bar c is allowed to work freely up and down in the guide or socket, and said parts form the only positive connection of the finger-liar to the frame A.

M is a sickle of the usual reciprocating kind. This sickle is fitted to the finger-bar in the ordinary or in any proper way, and its inner end is connected by a pitman, N, with the crankpulley b. The pitman N is formed of two parts, cl 0. One part, 01, is a socket or clasp, which receives the inner part, c. The part d has a longitudinal slot,f, made in its upper side, through which slot and the part c a screw or bolt, 9, passes, and the upper surface of the part e and inner surface of the upper side of the socket or clasp d are corrugated transverselyto prevent casual slipping. (See Fig. 2.) O is a chain, which is attached to the tinger-bar J and draft-pole P.

. On the frame A a box, Q, is placed. This box covers the whole of the gearing, as shown clearly in Figs. 1 and 2. On the upper surface of the box Q there are two parallel ways,

h h, said ways being near the outer side ofthe box, as shown clearly in Fig. 2. On these ways h h the supports 71 i of the drivers seat R are placed, as shown clearly in Fig. 2, the supports being allowed to slide freely on the ways, and prevented from moving casually by pinsjj, which pass through the lower parts of the supports and the ways.

By having the gearing arranged as shown the power is transmitted from the drivingwheel to the sickle in a very direct manner and with but little friction. The gearing also occupies an elevated position, free from out grass,grain, and all trash, and being in a position over the axle at the center of the machine, its movement or operation is easy, even when working rapidly. By having the pitman N formed of two parts, at c, as shown, the

. same may be extended or shortened, as occaplaced at any desired point of the machine necessary for a correct balancing of the same. What I claim as my invention,and desire to secure by Letters Patent, is-

The combination of the finger-bar having a bracket K and axial cross-head 0, with the socket-plate L of the frame A, the whole being constructed and arranged and operating in the manner and for the purpose herein described.

ROBERT BRYSON.
